A multi-objective optimization model for deficit irrigation schedule and its method

Based on the deficit irrigation theory, this paper points out the shortage of present models, then a new multi-objective model which thinks of planting risk is established, and a new method to optimize the irrigation schedule is presented in this paper. The method is to use staged fuzzy optimization theory and multi-dimension dynamic programming theory jointly. The case study proves that the model and the method are reasonable and practical and can be widely used in drought districts.
